There will be no unreasonable vases here. No sir.
If you are new to vases, you have 2 options:
1) Print as you normally do. You will get a solid model as is.
2) Set your slicer to vase mode. In Cura this is under special print modes, called "spiralize outer surface". The models here that have hollow spaces in the sides will not print properly in this mode.
These were generated from the attached OpenSCAD file. Give it a tinker.
